EK has revealed three new models of the EK-XLC Predator lineup. EK is going to release 140mm versions of their premium and expendable All-In-One CPU liquid cooling solutions. Existing 240 and 360 versions will now be accompanied by the upcoming 140 and 280 models.

The new flagship model of the 140mm Predator family is the EK-XLC Predator 280 with two 140mm EK-Vardar fans and EK-CoolStream CE radiator. Designed to work in harmony, EK-Vardar fans are high-static pressure fans developed specifically for EK-CoolStream radiators, which have a full copper core, superior to other alternatives on the market in terms of heat dissipation. In conjunction with EK-Vardar fans the result is increased performance across an entire fan operational range, thus delivering results both at low- and high airflow operation.

You can kinda use these that way already. THe ek have a quick release. You can purchase the gpu block with quick disconnects and attach it in line to the predator line and it will cool both. From my understanding it does a REALLY good job as well. I wouldn't say as well as a custom loop as you can add more rad space but its very very efficient. Beats most other CLC/AIOs for sure.
